Auto Loan Interest Calculator Formula

Most Auto Loan Interest Calculators will use the standard EMI formula.

EMI = [P x r x (1 + r) n ] / [(1 + r) n – 1]

EMI = Monthly repayment

P = Principal loan amount

r = Monthly interest rate (as a decimal)

n = Number of monthly repayments

To calculate the monthly interest rate divide the annual interest rate by 12 and then by 100.

So for 6%, r would be:

r = 6 / (12 x 100) = 0.005

To calculate the total repayment amount:

Total Repayment = EMI x n

To calculate the total interest:

Total Interest = Total Repayment – P

This will give you an idea of how much interest you will pay in total over the full repayment period.

If it is a simple interest loan, this could be different. However, this formula will be accurate for a standard Auto Loan.

Example Calculation

Let’s say you are going to take out a loan to buy a car. You want to know how much interest you will pay.

Loan Details:

Loan Amount $20,000

Annual Interest Rate 6%

Loan Period 5 Years

Number of Monthly Repayments 60

Using the standard EMI formula you can calculate that you will pay around $386.66 per month.

Breakdown of Repayment:

Monthly Repayment $386.66

Total Repayment $23,199.60

Total Interest $3,199.60

Loan Amount $20,000

These are just estimates and rounded. Assuming a fixed interest rate of 6% per annum, monthly repayments and without any additional fees, taxes or insurance.

This shows that you will be borrowing $20,000 over five years at 6% interest could result in approximately $3,200. If you compare different interest rates and/or loan periods you can see how you can reduce your borrowing.

What does my result mean?

Once you have used the Auto Loan Interest Calculator have a look at the following:

1. Monthly repayment – This is how much you will pay per month towards your Auto Loan. This will typically include both principal and interest.

2. Total interest – This is how much you will pay in interest to borrow the loan. This will not include any charges.

3. Total repayment – This is how much you will pay in total including principal and interest.

4. Principal – This is how much you originally borrowed. The higher your principal, the more interest you will typically pay.

5. Interest rate – If you have calculated multiple scenarios you can compare how much interest you will pay based on the interest rate. The lower the interest rate the more you can save.

Can you afford the loan? Check if you can fit the monthly repayment into your budget. This will include insurance, fuel, servicing etc.

A lower monthly repayment does not always mean you will pay less. A longer loan period may mean you pay less per month but more in total.

Factors Affecting Results

There are many factors that can affect how much interest you pay.

Loan amount – The higher the principal the higher the total interest will typically be.

Annual interest rate – The higher the interest rate the more you will pay to borrow. Lower interest rates will typically mean you pay less.

Loan period – The longer the loan period the more interest you may pay.

Deposit – The larger your deposit the less you will borrow.

Credit History – Your credit score and financial status can affect the interest rate.

Repayment – How often and when you repay will affect how much interest you pay.

Extra repayments – If you pay extra towards your principal this can reduce your future interest.

Fees – Fees and charges can increase your borrowing.

Interest rate – If your interest rate changes this may affect how much you actually pay.

Understanding these factors can help you to compare different offers and make the best decision when borrowing.
